CLAMP-HOOK.

SPECIFICATION forming part of Letters Patent No. 768,377, dated August 23, 1904.

Application filed March 28, 1901. Serial No. 53,176. (No model.)

To all whom it may concern:

Be it known that we, CHARLES KNIBBS and ROBERT H. STERRETT, citizens of the United.

vented a new and useful Clamp-Hook, of which the following is a specification.

Our invention relates to a-clamp-hook, and particularly to a clamp-hook for use in connection with the shafts or bars for supporting the heddles in a loom-harness.

The object is to provide a hook which may be readily applied to and removed from the bars, either for purposes of spacing them, suspending them, or sustaining weights from them; and it consists, broadly, of a rod of spring or malleable metal having a loop formed at one end. capable of being sprung open to apply the hook to the bar.

A practical embodiment of our invention is represented in the accompanying drawings, in which Figure 1 represents the clamp-hook in side elevation with the end opposite the loop left straight to be turned either into hook or eye form or screw-threaded, as may be desired. Fig. 2 is a view of the same in edge elevation. Fig. 3 is a view in side elevation, showing the rod provided with an eye at the end opposite .the loop; and Fig. 4 is a view showing the manner in which the hooks may be applied to the heddle shafts or bars.

The rod of metal which forms the clamphook may be either round or polygonal in cross-section, as may be desired, and may be formed of anyone of the several well-known metals or metal alloys-such as steel, brass, coppertempered to the proper stiffness to permit of the loop being opened to slip the parts over the heddle shaft or bar of'theloomharness.

The shank of the clamp-hook is denoted by a, and. the loop at its upper end is formed by turning the shank a outwardly a short distance, as shown at b, then extending it upthe desired width of the loop, then bringing it downwardly, and, finally, inwardly toward the shank, as at d, and then continuing it downwardly, as at e, in proximity to the Shank a. The part 6 may be flattened or made convex on the side toward the shank a in order to rest in close proximity to the shank.

When employed for connecting the lower bar to a weight or harness, the shank may be provided with a lateral projection conveniently formed by giving the shank one complete turn, the said projection serving to sustain the hook in its guide when for any cause it is temporarily released from the bar.

The hook as thus formed may be sold as an article of manufacture for the purposes of use in connection with a loom-harness, either for suspending the heddle bars or shafts or hanging weightsto the shafts or in forming Spreaders for the shafts, its end opposite the loops being in each instance modified to suit the particular use to which it is to be put.

'What weclaim is- A clamp-hook for loom-harness comprising arod of spring metal. developed at one end into a loop capable of being sprung open to receive and release a bar, the opposite sides of the loop being outside the plane of the Shank, and the free end of the loop being. fitted to rest when in its normal position partially within the plane of the shank, substantially as set forth.

In testimony that we claim the foregoing as our 1nvent1on we have signed our names, in presence of two witnesses, this 14th day of O. S. SUNDGREN.
